Sasha's Linux Applications and Utilities

This page contains a collection of Linux applications and utilities I have
written. I wrote them to solve a particular problem, and then decided to
share. They will compile with gcc 2.95, and will need some fix up to
compile with newer compilers. Unfortunately, I have not had the time
to fix them up.

libtcp++ is a C++ class library to facilitate the creation of TCP/IP clients and servers.
It has three
classes, TcpClient, TcpServer and TcpIpRuleSet. TcpServer has build it logging capability
peer detection method, and IP-based access control in addition
to regular server functionality. TcpClient supports a user specified timeout on connect(),
nice for port/host scanning, and other situations when you may be connecting to a dead
host or a firewalled port. Download it from here Despite the lack of doucumentation,
the sources contain examples that should help you figure it out.

Simple non-caching HTTP proxy. Great for
situations when the official route between two hosts is down/slow/firewalled
, the routers cannot be reconfigured, and you need to look at a page on the one
host from the other. In addition, it now supports
user-agent spoofing (there are a few sites that play a smart alec and will not
show you pages unless they like your User-agent), and filtering the content
with a custom filter application.

I wrote this to be able to access a news server that would not allow me to connect
from my machine, but would from another that I had access to. It a daemon that
listens on a port for connections, and when the connection is made, proxies/bounces it to
the host/port pair specified in the config file unmodified. Very simple, but very useful when
you need to get around a bad route/firewall. Latest version has IP-based access control option.
